I got one of these for a 9.75 , Ford factory sealed,, and its made by Koyo. ST-3376. Never heard of Koyo. Plus I googled this p/n and couldnt' find anything on it at all. (the big rear brg is timken) Anyone heard of or have used Koyo???? thanks rossford

they seem like a decent company. timken doesn't really mean much these days. they allow other manufacturers to produce their products.
